I have used Hornady 308 Match brass, it way better than their standard brass! I also used Hornady 338 Lapua brass, while better than PPU and some of the others it is just not in the same League as Lapua.
I have used Starline brass in 45-70, 45 Colt, 44 Mag and several other head to head comparisons, Starline has always came out better! Better in Longevity and initial quality, consistency of length and wall thickness!
Unless you have proof that Hornady is making the 460 on the Match production line, go for the Starline!
